ABSTRACT:
A printer has a print head with multiple nozzles and firing elements for corresponding nozzles. The print head receives one or more power supply inputs to operate the firing elements. The print head has power supply fault protection circuitry to guard against harmful and destructive effects on firing resistors resulting from power supply fluctuations. The power supply fault protection circuitry is integrated into a pen-based chip that also forms the firing elements and optionally the firing logic.
